Just an additional remark, I can actually set the DPMS state in /sys/class/drm/.../dpms back to "On" with (through SSH): XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr --newmode 1280x1024 108 1280 1328 1440 1688 1024 1025 1028 1066 +HSync +VSync XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr --addmode VGA-1 1280x1024 XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr --output VGA-1 --mode 1280x1024 XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xset dpms force on However, the display will stay remain turned OFF. Adrian What I posted here may be useful for this bug: https://bugs.freedesktop.org/show_bug.cgi?id=31122#c4 Could you test out https://bugs.freedesktop.org/attachment.cgi?id=84946 and see if it helps? I have unfortunately sold the Mac in question already. However, I might be lucky to borrow an identical one to test the patch tomorrow. I will report back in any case. There are also some more PPC Macs which I can borrow for testing.

Created attachment 64544 [details] Kernel log (dmesg) Hi, I have been running Debian Linux on a Apple PowerMac G4 "Quicksilver" (Model: M8493) with the following main hardware specifications: - PowerPC G4 7450, 867 MHz - 1GB main memory - nVidia GeForce GeForce2 MX/MX 400 (NV11) AGP video adapter Software environment: - Debian Linux PowerPC unstable - Kernel 3.4.4 (from Debian experimental) - nouveau X.org driver 1.0.1 - libdrm: 2.4.33 - mesa: 8.0.3 Problem description: When using nouveau, the video adapter permanently turns off the attached display through DPMS. This cannot be reversed and I do not get back video until I reboot the machine by logging in through SSH. I can neither switch to a virtual text console using <Ctrl>+<Alt>+<F1..Fn>. The video output is fine when preventing X from starting and using just a virtual text console (KMS works fine as well). xrandr does not any displays attached, see attached logfiles and xrandr output. I'm attaching the following files: - kernel log (dmesg) - Xorg.0.log - lspci output - xrandr --verbose output - vbios.rom (cp "/proc/device-tree/pci@f0000000/NVDA,Parent@10/NVDA,BMP" ~/vbios.rom) If you need any further input, please let me know. The machine is a sole test machine, so I'm happy to try any code from git or run any quirky code. Cheers, Adrian
